The Propagation method of Broad Leaf Top Ten efforts

The broad leaves are evergreen all the year round, the tree shape is elegant, the branches and leaves are strange, and the flowers and colors are beautiful, so it is very suitable for ornamental tree species with greening. Can be used to decorate courtyards, water pavilions, etc., often with rocks. According to the research and determination, the tree is resistant to polluted gas and can be used for greening in industrial parks. It can also be planted around rural orchards and vegetable gardens for viewing and harvesting medicinal materials with good results.

The methods of propagation are divided into seed propagation, cutting propagation, split propagation and transplanting.

1. Seed propagation

The fruit ripens in late November. Do not thresh the fruit in December. Pile them up for a period of time before ripening. Peel the fruit, remove the seed, dry it and mix it with wet sand for the winter.

After the seeds are harvested, the seeds need to be stored in wet sand and placed in certain containers or dug holes to deal with the seeds. The seeds were sown from March to April of the following year. Make a shallow trench on the seedling border, 7cm the distance between the ditch and 25cm, sow the seeds evenly as in the ditch, and cover the soil gently. Hole sowing is also used in some places. The distance from acupoint to 20cm is about. Sow about 4 seeds per hole, cover soil with 6cm or so, and sow 20kg per 0.067hm2. Burrowing saves seeds. Keep the soil moist after sowing, and seedlings can emerge in about 2 weeks. Uncover the grass step by step, shelter in summer, strengthen fertilizer and water management at seedling stage, leave bed or separate planting in the second year, and semi-shade environment should be selected in large nursery. The seedlings will not blossom until 4-5 years after planting.

2. Cuttage propagation

The cuttings in the open field should be carried out in late March. The sturdy stems with deciduous leaves in winter should be used as cuttings, cut off by 15cm, inserted into the loose sand, buried in deep 10cm, and shaded by Reed curtains. In the north, softwood cuttings should be used from June to July, the cuttings should be long 10~12cm, a compound leaf at the apex should be retained, and the leaflet at the apex of the compound leaf should be cut off. Leave only two basal lobules and cut them off 1 / 2, insert them into the Dahua River with plain sand and bury them into the deep 5cm. Shade maintenance, new roots can grow after autumn, separate seedlings on the pot before winter, and then move into the cold room to survive the winter.

3. Ramet propagation

Ramet can be carried out from mid-October to mid-November or from late February to late March. The stems of the ten meritorious works grow upright and upright, and the branching power is weak, and the cuttings need to be cut off during cuttage propagation, so that the mother plant can not be seen temporarily, so it is often combined with turning the basin and changing the soil, separating the whole clump of plants, planting in the pot, and truncating the original stem after survival to promote the root system to sprout new roots and form new clumps of plants.

4. Transplanting

The seedlings need to be cultivated in the seedling bed for 2-3 years, when the seedling height is 3-4 cm, the seedlings can be transplanted in spring or autumn, generally from March to April every year, and from September to October in arid and semi-arid areas. Stay in the soil or with mud balls, easy to maintain and manage, pay attention to pruning dead branches and keep the plants clean and tidy. Dig up the seedlings before planting and cut off part of the leaves to reduce the evaporation area and make 130cm. The length of the border is determined according to the number of seedlings and the topography. Plant one plant in each row according to 30cm, fill the soil to the ground level, pour the root water, and cover a layer of soil moisture after water infiltration.

In addition, the method of sexual reproduction of the ten seeds can be carried out according to the following steps:

Seed harvesting: harvest when more than 60% of the fruit in an inflorescence is purple-black.

Peeling: take off the seed coat of the ten fruits of the long column and get the seeds.

Weighing: weigh the seeds of ten great achievements of the long column.

Drying: put the long column seeds in 20 ℃ ~ 30 ℃ to dry naturally, so that their water content is reduced to 20% 30%.

Sowing and management: select the loose soil, sow according to the row spacing of 5cm × 5cm~10cm × 10cm, the sowing depth is controlled at 3~5cm, then cover the soil, thoroughly irrigate the rooting water, cover with plastic film, and adopt the conventional method to carry on the breeding management, after 1 month to 2 months, it can sprout.
